The age make it "crap", but not in the way you think. I can speak about C++. C++ code wrote in the older standard, let say C++ pre-11, who are 20 or more years old make it difficult to maintain because new generation of programmers are not generally interested to legacy code or in learning old c++ standards and skilled programmers don't want be relegated to be eternally maintainer of old projects. For this reason projects die by asphyxia. We have that good code base in Cobol, ok, but the point is: who cares ? Who is important when you need new programmers. Besides, a part considerations on the language, the architecture is important we live in a world of microservices and old code not updated to modern paradigms could became "crap", even if if the most elegant code.
